Answer:
2:1
Step-by-step explanation:
90-60 = 30 red marbles
blue:red → 60:30 → 2:1
8 can go into 66 about 8 times. It doesn't come out as a whole number. 66 ÷ 8 is 8.25 to be more exact.
(17x+19)+(19x-15)=180
36x+4=180
36x=176
x=44/9 which is approximately 4.8
mmTherefore mmmIn conclusion m
Answer: 3.16 units (Option C)
Step-by-step explanation:
The key to this problem is to use the distance formula, which is:
Distance = 
The first point, T = (x₁,y₁), and the second point, U = (x₂,y₂).
Plugging the two points into the equation, we get:
Distance = 
The values within the parenthesis are subtracted:
Distance = 
The values are then squared:
Distance = 
Finally, they are added together:
Distance = 
can be approximated as 3.16, so the distance between the two points is 3.16 units.
